CAUTION
Hot water can escape from tank causing
injury. Operate relief valve or remove
drain plug only when the tank water is
cold.
• Also, open the Pressure-Temperature Relief
valve at the top right portion of the tank to
prevent air locking in the tank while draining.

Fill Drainage System P-Traps
14. Pour about one cup of RV antifreeze down
each drain for the galley sink, lavatory sink,
and shower/tub. This fills the drain trap pipes
to prevent holding tank odors from entering
the coach during storage.
Dump and Clean Holding Tanks
15. Completely drain the sewage and waste water
holding tanks at an approved waste disposal
site. Drain the sewage tank first so the
following waste water can rinse any waste
solids from the dump outlet and sewage drain
hose.
16. Close dump valves and refit the dust cap onto
the drain outlet. This will inhibit rust
formation on valve shafts and prevent entry
and contamination by airborne debris, insects,
and rodents.
Your drainage and fresh water systems are now
winterized.
See instructions for removal from storage in
Section 11 - Maintenance and Storage.
